Young Justice is a new TV serie from DC comics universe. It's presented, like another animated serie, with 26 episodes with some introduction of  unknown character by the non fans.

There animated TV serie is based on young heroes who are sidekicks of well known great JLA heroes, even by non fans.

If I talk to you about Wonder Woman, Batman or Superman, even Flash... You know in few seconds what I talk about. Soon you will know some more heroes like Blue Beetle or Green Lantern who arrived through theater or TV show.

All non fans will be aware about them if you talk about these heroes, even for some who don't see the movie or TV serie. For youngest people it will be different because we introduce to them since a long time a lot of super heroes from DC Comics. Who don't know  Robin who help Batman ???

Now it's time for the new Superboy, a clone of Superman, teaming with  Robin and Kid Flash, also Aqualad follow them. Another heroes will be equally in as mentors like Batman, Red Tornado and Black Canary.

Story will be in Earth but not the one you think. It's an another Earth from a another dimension who was tagged as Earth-16. Here heroes live as Hollywood stars and young heroes are new in this huge JLA organization... But it's not like they are a full member of the team, they are just little member with tiny access to JLA. So they were upset and began to hack some data from JLA database to prove their valor in a real big mission. One of them leave this fake tiny team. others stayed to accomplished a big mission to impress the old heroes.

After their action, they obtain their own missions and own offices in an old headquarter of JLA. of course they have some mentors with them to be trained and sometimes to fight very big and accurate villains.

As you realized this serie talk to young people but equally to all fans of superheroes because they find a good rythm, a serious ton and scenarii are very good too. So the result of this work is rewarded with the first place as leader of their scheduled broadcast in USA.

For me, I really think it's a good animated TV serie which could satisfy both fans and non fans of superheroes and I'm sure it's could watched by your child with this serie with a lot of rythms and non free violence.
